摘要: 针对现有水下航行体实航工作可靠度评定方法的局限性, 根据实航试验所获取航行时间、成败试验结果的数据特点, 将指数分布与二项分布结合起来, 建立了水下航行体实航工作可靠度的等效评定方法, 解决了现阶段水下航行体实航工作可靠度评定方法中缺失规定时间的问题, 拓展了试验数据的利用效率, 可客观评价水下航行体的实航工作可靠度, 评定结果更接近实际。

Abstract: To improve the existing evaluation method of running working reliability for an underwater vehicle, an equivalent evaluation method of running working reliability for an underwater vehicle is proposed by combining binomial distribution and exponential distribution according to the data of running time and success/failure data obtained from sea trial. The pro-posed method can solve the problem of lack of given time in the existing evaluation method, improve test data utilization, evaluate the running working reliability of an underwater vehicle more objectively and accurately.
